That would be really old gumstix boards, from a few years ago. If you
bought it 2 weeks ago, then it would have a u-boot that supports SD
cards (at least some).

Once you've past this stage, if stuff doesn't work - powering off or
resetting will brick your gumstix.

The only other thing to try would be to use $filesize, but since you
used the reset command withtout successfully writing u-boot its too
late.

If you bought it 2 weeks ago, it doesn't have the JTAG signals in the
60-pin connector.

The later versions of the gusmtix have the JTAG signals brought out to
pads on the gumstix itself.
There is a older schematic (rev 814) of the JTAG that was intended for
the connex series, but I don't think gumstix made any boards. Anyways,
you should be able to determine the approximate location of the
various signals from that (each of the TP locations should correspond
to pads on the motherboard).
